Steca Solarix Sinus

550 I, 550 RI, 900 I; 900 RI


The sine wave inverters of the Steca Solarix series have already proven themselves in over 15,000 applications. The locations where these units are used span the globe.

The compact design and optional integrated solar charge controller make this an easy-to-install plug and play solution. A button on the front of the unit allows the user to select between an automatic load detection mode, continuous operation of the unit, and a sleep mode. This means that standby consumption can be considerably reduced, which is particularly important for systems in islanding operation.
